How easily can the pencil marks be erased and not seen? (Dark or light marks?) Would you consider $20,including shipping, for The Next 10, Actual Official LSAT PrepTests and Superprep - and I'll do my own erasing to save you the time and trouble? If so, how soon could you ship, from where and what method? I need to know how long it would take to get them. I live in Vancouver, Washington - 98683.
